Application led December 2, 19x15. l Serial No. 64,725.

To all whom t may concern:

Be it known that we, MELCHIOR MILLER and ALFRED D. BURG, citizens of theUnited States, residents of Le Mars, county of Plymouth, State of Iowa,have invented certain new and useful Improvements in Wrenches, of whichthefollowing is a speci,-

.fication pointed out in the claims.

In the accompanying drawings forming part of this specification, Figure1 is a side view of awrench embodying our invention, partially insection, Fig. 2 is a view ofthe wrench, looking toward the openingbetween the jaws, Fig. 3 is a sectional view on the line of Fig. l, Fig.4 is a sectional view on the line y-y of Fig. 2.

In the drawing, 2 represents the shank of the wrench, having jaws 8 and4 formed thereon in a plane at rightl angles to the axis of the shankand having a socket 5 formed between them that is adapted to receive abolt" head or bur on which the wrench is used. vWe propose to providewrenches of different sizes having sockets of varying width to adaptthem for the different sizes of burs and bolts and preferably thewrenches will be sold in sets of a suitable number, with sufficientvariation in the sockets to adapt the tools for all burs and bolts thatmay be encountered in a machine or vehicle.

The end of the shank 2 opposite the jaws has ears 6 formed thereon witha space 7 between' them to receive a tongue 8 formed on the end of ahandle 9 having shoulders l0 which are seated on the rounded ends of theears. The tongue 8 has aV curved surface provided with ratchet teeth 11and a pin l2 passes through the ears 6 and through said tongue andsecures the parts together. A latch 13 is mounted in a socket 14 in thesitions where shank 2 and provided with a spring 15 which yieldinglyholds the tapered end of the latch in 'engagement with the teeth of theratchet. This handle 9 is free to swing through an arc of 180 degrees,as indicated by the full and dotted lines in Fig. 1, and may thereforeshank 2 or in line therewith, or at any angle intermediate to the fulland dotted line position. adapts the wrench for a variety of uses. Itmay be thrust in between the spokes of a wheel or pulley and can beinserted in poit would be utterly impossible to use a wrench of theordinary type.

The handle is preferably provided with an end portion 16 having holes 18extending therethrough at right angles to one another into which a punchor other suitable article may be inserted for the purpose of forming anauxiliary handle when the handle proper is in alinement with the wrenchshank. The ratchet device will hold the handle in its different adjustedpositions and provides a flexible joint which permits the convenientmovement of the handle either to the right or the left, according to theposition in which it is desired to place the wrench In various ways thedetails of construe'- tion herein shown and described may be modifiedand still be within the scope of our invention.

We claim as our invention:

1. A wrench comprising a shank having jaws formed thereon in a plane atright angles substantially to the axis of said shank, a handle hinged onthe other end of said shank and provided with a hand grip, said handlehaving holes extending therethrough in which a supplementary handle maybe inserted, 'the hingedy connection of said handle with said shankpermitting it to be adjusted at an angle thereto, and means for holdingsaid handle in its adjusted positions. Y

2. A wrench comprising a shank having a substantially fiat diskeccentrically mounted on one end of said shank in a plane aty rightangles substantially to the longitudinal axis of said shank, said diskhaving a recess in one side thereof extending inwardly to a pointadjacent the center of said disk and the wall of said shank, the wallsof said recess forming jaws for gripping a nut or bolt-head insertedinto said recess, a

be set at right angles to the hand grip -pivotally connected With theother end of said shank and free'to swing to a position in alinementWith said shank or 'angularly With respect thereto, and means forholding said hand grip in its adjusted position, for the purposespecified.

3. A Wrench comprising a 'shank having a disk eccentrically mounted onone end of said shank in a plane at right angles substantially to thelongitudinal aXis of said shank, said disk having a recess in one sidethereof extending inwardly to a point adjacent the center of said diskand the Wall of said shank, the Wall of said recess forming jaws forgripping a nut or bolt-head inserted into said recess, a hand grippivotally connected With the other end of said shank and free to swingto a position in alinement with said shank or angularly With respectthereto, for the purpose specified.

AIn Witness whereof, we have hereunto set our hands this 27 day ofNovember 1915.
